Orangutans
Top 4 in Top 10 World's Most Solitary Animals
Orangutans are intelligent primates with striking red coats that live in semi-solitary groups in the wild. Their long, strong arms, gripping hands, and grasping feet help them to travel quickly among the branches, which is why they spend most of their time hanging out in trees.
Because the male and female orangutans' home grounds overlap, the two sexes may come into contact briefly while moving about and foraging. In enormous fruiting trees with an abundance of fruit, orangutans will occasionally congregate and eat. The offspring of adult female orangutans, who are dependent on their moms for at least six to seven years, also travel with their mothers.
